The corn and soybean crops are halfway through their life cycle and are currently in the most critical phase of growth. Final yields will be determined by a combination of soil-plant processes that are highly affected by the prevailing climatic conditions in August, existing status of the soil water and nitrogen reserves, biomass production and N uptake to date, and biotic factors such as insect and disease pressure.
